The Fluent Immigrant turns YouTube, Netflix and Prime Video subtitles into interactive English lessons for Portuguese and Spanish speakers. Click any word in the subtitle to see its meaning, hear it, and save it to your vocabulary. Every saved word becomes a flashcard with spaced repetition, so what you learn while watching actually sticks. Dual subtitles (English plus your language) are one click away. You already watch a lot of English. YouTube at lunch, Netflix at night. Almost none of it sticks, because you never do anything with the words. This extension is where you do something with them. 📺 Interactive subtitles on the sites you already use

🎨 See how much English you already know Every word in the subtitle is coloured by how well you know it:

White: new word
Green: you recognise it when you hear it
Orange: it is yours, it comes out without thinking

Open any video and see, in the line itself, how much of it you already own. 🌍 Dual subtitles, when you want them

The translated line in Portuguese or Spanish, under the English original
Hidden by default. Turn it on for the hard parts, off for the rest
Watching something in Portuguese or Spanish? It flips around, and the English becomes the clickable line

🔁 Vocabulary builder and flashcards

Words you mark go straight into your Fluent Immigrant vocabulary
